Active clinical trials for "Intracranial Aneurysm"

The primary objective of this study is to evaluate the effectiveness and safety of robotic-assisted endovascular embolization procedures compared to objective performance criteria for traditional, manual operation based on the scientific literature.

An aneurysm is a bulge in a blood vessel caused by a weakness in the blood vessel wall, usually where it branches. As blood passes through the weakened blood vessel, the blood pressure causes a small area to bulge outwards like a balloon. Most brain aneurysms only cause noticeable symptoms if they burst (rupture). This leads to an extremely serious condition known as a subarachnoid hemorrhage, where bleeding caused by the ruptured aneurysm can cause extensive brain damage and symptoms. The study aims to evaluate the safety and effectiveness of a medical device to treat brain aneurysms.

Cerus Endovascular is sponsoring a prospective, multi-center trial to document the safety and performance of the Contour Neurovascular System™ ("Contour"). The purpose of the study is to document safety and performance of the Contour in treatment for patients with intracranial aneurysms (IA). The data from the study will be reported as a Pre-Market study to the Notified Body to support CE Mark approval.

This study was designed to identify high platelet reactivity (HPR) who might have in-stent thrombosis in unruptured aneurysm with intracranial stent placement with light transmittance platelet aggregometry (LTA). For HPR patients, higher ischemic stroke rate maybe occurred, and we hypothesis that dose adjustment of aspirin and clopidogrel based on LTA monitoring maybe reduces the rate of ischemic stroke compared to a standard strategy after intracranial stent implantation at early periprocedural period and 1 month follow-up period.

The primary objective of this study is to demonstrate effectiveness and safety of the Neuroform Atlas Stent System for use with bare metal embolic coils.

Phase 1/2a Multicenter, Controlled, Randomized, Open Label, Dose Escalation, Safety, Tolerability, and Pharmacokinetic Study Comparing EG-1962 and Nimodipine in Patients with Aneurysmal Subarachnoid Hemorrhage

The purpose of this study is to evaluate the safety and efficacy of the Low Profile Visualized Intraluminal Support(LVIS™ and LVIS™ Jr.)devices from MicroVention, Inc. when used to facilitate endovascular coiling of wide-necked intracranial aneurysms with coils.

Rupture of brain aneurysms is a common cause of death and disability, accounting for as many as 10% of stroke cases in the United States. While much of the resulting injury to the nervous system is caused by the initial bleeding from the aneurysm, many of these patients develop cerebral vasospasm, pathological constriction of the blood vessels supplying the brain, several days following hemorrhage. As many as a third of patients can suffer a resulting neurological deficit and stroke, presumably caused by the decreased blood flow to the brain (ischemia). This delayed brain injury accounts for a significant percentage of poor outcomes following aneurysm rupture. Studies have shown that remote ischemia to many organs can precondition other tissues (including the brain) to be more tolerant to decreases in blood flow. This "remote ischemic preconditioning" has the promise of protecting the brain from ischemic injury. Whereas in other forms of stroke the onset of ischemia cannot be predicted in the general population, following aneurysm rupture the investigators know which patients are likely to develop vasospasm and when. Therefore, ischemic preconditioning following aneurysm rupture may help prevent some of the ischemic injury caused by vasospasm. Remote ischemic preconditioning by transient limb ischemia (produced by inflation of a blood pressure cuff on the arm or leg) has been shown to minimize injury to other organs, most notably the heart. Remote ischemic preconditioning of the brain following aneurysm rupture has not yet been investigated.

The purpose of this study is to evaluate the safety and short-term effectiveness of implantation of 'Flowise Cerebral Flow Diverter' for the treatment of unruptured wide-necked cerebral aneurysm in the internal carotid artery.
